DISK PLOW.

Specification of Application filed November To all 0.7mm t may concernBe it known that-.1, lli/liviana C. Fonn, a e citizen of the UnitedStates, residing at Frick, in the county of Beckham, State of Oklahoma,have invented certain new and useful Improvements in Disk Flows, and ldo hereby declare the following to be a full, clear, and exactdescription of the invention, such as will enable others skilled in theart to which it appertains, to make and use the same.

This invention relates to disk plows.

The object of the invention resides in the provision of a disk plowembodying` an improved construction, whereby the cultivator disks andthe traction wheels may be adjusted relatively so that the latter willalways travel in the furrow formed by the disk in advance thereof.

A further object of 'the invention resides in the provision of al diskplow embodying an improved construction for yieldingly holding the disksin engagement with the ground so that when the disks are brought intoengagement with a relatively hard substance, such as stones, or rocks,they will TWith the above and other objects in view, the inventionconsists in the details of coni struction and in the arrangement andcombination of parts to be hereinafter more fully described andparticularly pointed out in the appended claim.

In describing the invention in detail, reference will be had to theaccompanying drawings wherein like characters of reference denotecorresponding parts in the several views, and in which:

Referring to the drawings, theimproved disk plow is shown as comprisingan axle 10 including a central arch portion 11. Adjustably ixed on theaxle 10 are. traction wheels 12 and 13. Secured to the axle 10 againstrespective sides of the arch 11 are Letters Patent. patented May 3,1917.

forwardly'extending tongue straps 14v and )15. between the forward endsof which is secured a block 16 and pivotally mounted upon this block isa draft tongue 17. Secured to the tongue 17 are rearwardly extendinghandles 13. Secured against the underside of the block 1G is the upperportion of an arch 19, the terminals of which carry bearings 2O in whichis rotatably mounted a disk arch 21. The arch 19 is strengthened bybraces 22 connecting same with respective tongue straps 14 and 15.Adjustably mounted on each end of the arch 21 is a clamp or clip 22,including an l.- shaped plate 23, one arm of which is disposed upon thetop of the clamp while the other armI thereof depends. Extending throughthe depending arm of each plate 23 are bolts 211- and 25, the opening inthe depending arm through which the bolt 24C extends being extendedlaterally. Mounted on the bolts 2l and 25 are clamping plates 26 and 2T,and secured between the plates 26 and 27 is the arm connecting portionof a substantially U-shaped bracket 23. Mounted upon the arms of eachbracket 23 by means of clips 29 is a disk axle 30 and rotatably mountedupon this axle is a disk gang 31. By this construction it will beobvious that the clip or clamp 22 can be adjusted on the arch 21 andalso that the bracket 28 can be adjusted transversely of the machine. Bythis adjustment the disk gang 31 can be readily brought-into a positionjust forward of the adjacent traction wheel so that the latter willtravel in the furrow formed by the outer disk of the 33H3-,

Fixed upon the upper portion of the arch 21 is a bracket 32, in which isslidably mounted for movement longitudinally of the machine the stem 33of a Y-shaped member 341-, a nut is threaded on the forward end of thestem 33 and a spring 36 encircles said stem and bears at one end againstthe nut 35 and at its other end against the bracket 32. Carried by thebracket 32 is a transverse member 37 and pivoted on this member' 37 arearms 33 which have secured to their free ends a shield 39. Secured tothe rear end of the shield 39 is one end of a chain 10 which is adaptedto be engaged over a hook (l1 to raise and lower the rear end of theshield. The arch 21 is adapted to be rotated to raise and lower thedisks 31 and also to raise and lower the shield 39 by means or anoperating lever 42 having its lower end forked to form arms 43 and 44which are pivotally connected to the tongue straps 14 and l5 and alsoconnected respectively to the arms of the Y-shaped member 34.

In the event the disks 31 engage a relatively hard substance it will beapparent that the arch 2l can rotate independent of the operation of thelever 42. During rotationot the arch 2l independent of the.;

lever 42 the spring 36 will be compressed and as soon as the disks 3lhave passed over the relatively hard substance they will be returnedinto proper engagement with the ground by said spring.

The operating lever 42 carries a spring pawl 45 which cooperates with atoothed member 4G secured to the block 16 and thereby said lever islocked in a desired adjustment.

Secured to the straps 14 and l5 respectively are corresponding ends oibraces 47 which are held against the arch 11 by means of a clip 4S andhave mounted on their eX- treme rear end in an adjustable manner anoperators seat 49.

Copies of this patent may be obtained for five cents each,

What is claimed is: v I A disk plow comprising a wheeled axle,

a iframe supported by said axle7 a disk arch 0 pivoted on said frame7clamps secured to respective ends of the disk arch, each of said clampsembodying a block and a U- shaped member embracing the arch and havingits arms extending through passages in the block, an L-shaped memberhaving one arm bearing upon and provided with openings through which thearms of the clip eX- tend, the other arm of the L-shaped inemberextending downwardly and provided with an upper arcuate slot and a loweropening, bolts engaged. through the slots and opening respectively, aplate engaged on said belts, a U-shaped member secured between the plateand the adjacent arm of the l..- shaped member, an axle mounted on theU- shaped member, and a disk gang mounted on the axle.

ln testimony whereof, I aiix my signar ture, in the presence of twowitnesses.
